Deployment notes

Static media files are served using Nginx, which serves as a reverse proxy. It sends requests for paths that do not exist on the disk to Gunicorn server.

Gunicorn listens on port 8080. nginx.conf proxy_pass is set to 8000 django dev server, so this needs changing for deployment.

Another important bit of the config file is:

add_header Access-Control-Allow-Origin...

This allows the Chrome tagging extension to get on with the AJAX Cross Site Scripting(XSS) security controls.

Tagging extension

Tagging extension for Google Chrome has a bit of configuration on top of the tag.js file. Unpacked code is in the /tag folder.
